ATTORNEY Patented Aug. 8, 1939 UNITED STATES PATENT OFFICE Application April 11,

4 Claims.

This invention relates to new and useful improvements in a smokers dry pipe pin.

More specifically, the invention proposes the construction of a dry pipe pin characterized by 4a length of wire bent intermediate of its ends and having a pair of diverging fingers engageable into the smoke passage of a stem bit at the union between the bowland stem, and upon one end of which a cylindrical filter member is mounted for extending into the smoke passage of a bowl section oi a pipe at the union between the bowl and stem for absorbing the moistures from the smoke, and for keeping the heel of the pipe bowl dry.

Still further it is proposed to arch portions of the length of wire which are adapted to engage the cylindrical i'ilter member for the purpose of centering and suspending the filter in the stem of the bowl to absorb moisture from the smoke, and still allow a free passage for the smoke through smoke passage.

Another object of this invention is to form the wire, at its intermediate portion, with an end loop and bulged out portions between which the cylindrical filter member may be engaged for holding it in position within said smoke passage.

Still further it is proposed to form the filter member from filter paper or other similar absorbent material which is rolled into a cylindrical shape, and which has its outer edge extending radially therefrom for contacting the bottom wall of the smoke passage to lift the moisture olf the bottom wall and carry it to the body of the filter member.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a materiai part of this disclosure:

Fig. l is a cross section of a pipe having a dry smoke pin according to this invention inserted therein.

Fig. 2 is a side elevational View of the dry smoke pin per se.

Fig. 3 is a view looking in the direction of the line 3--3 of Fig. 2.

Fig. 4 is a perspective View of the pin and the filter in their separated condition.

Fig. 5 is a perspective View of the device.

The smokers dry pipe pin, according to this invention is to be used in conjunction with any average size pipe having a bowl Ill and a stem 193s,y serial No. 201,287

Il. The stem II comprises a bowl section Il and a stem bit section IIb. The adjacent ends of the bowl section and the stem bit section are connected together in end alignment by means of a reduced shoulder I2 formed on the Ainner end of the bit section and which is engageable into a complementary opening I3 formed in the outer end of the bowl section Ila.

The dry pipe pin comprises a length of wire I4 which is bent intermediate of its ends to have a pair of diverging iingers Illa which are engageable into the smoke passage I5 of the pipe and within this bit section at the union between said bowl and stem. A cylindrical filter member I6 is supported upon the length of wire at its bent intermediate portion and is engageable into the smoke passage I5 at the bowl section II a of the pipe. The base ends of the lingers I4a are formed with an oiTset portion which continues into corresponding elements for engaging and holding the cylindrical filter in position.

The cylindrical filter member comprises a piece of illter paper or other similar material which is rolled into the form of a cylinder and which is supported upon the length of wire for absorbing excess moistures from the smoke which passes through the smoke passage I5. The gripping elements for holding the cylindrical filter comprises an end loop portion |41), and a pair of oppositely disposed bulged out portions I 40 which are capable of engaging around the sides of said lter member. The end loop portion IIIa and the bulged out portions I4c are connected together by portions of the wire which are adapted to extend longitudinally along the side of the lter on either side of its end I5a for holding this end radially extended to contact the bottom wall of the passage I5.

The opening I3 is slightly longer than necessary to accommodate the reduced shoulder I2 formed on the inner end of the bit section,` as shown in Fig. 1, and the iilter member is adapted to extend into that portion of the opening I3 which extends beyond the end of reduced shoulder I2.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes andl modications coming within the scope of the invention as dened in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

l. A smokers dry pipe pin, comprising a length of wire having its ends formed into a pair of diverging fingers engageable in the smoke passage at the bowl end of the stem bit of a pipe to hold 5 the device in position, a cylindrical lter member for engaging in the smoke passage at the bowl section of the pipe stem, and gripping elements formed in said Wire and engaging said filter for holding said filter.

2. A smokers dry pipe pin, comprising a, length of Wire having its ends formed into a pair of diverging fingers engageable in the smoke passage at the bowl end of the stem bit of a pipe to hold the device in position, a cylindrical lter member for engaging in the smoke passage at the bowl section of the pipe stem, and gripping elements formed in said wire and engaging said filter for holding said filter, said gripping elements, comprising an end loop formed at the intermediate portion of said length of wire for encircling one end of said lter member, portions continuing from said end loop and extending along the side oi' said lter, bulged out portions continuing from the ends of said portions and engaging around the other end of said lter member, and offset portions continuing from said bulged out portions and extended over the end of said filter member, said fingers continuing from the ends of said offset portions.

3. A smokers dry pipe pin, comprising a length of Wire having its ends formed into a pair of di- Verging lingers engageable in the smoke passage at the bowl end of the stem bit of a pipe to hold the device in position, a cylindrical filter member for engaging in the smoke passage at the bowl section of the pipe stem, and gripping elements formed in said Wire and engaging said filter for holding said filter, said filter member comprising a piece of lter paper or other similar material rolled into cylindrical form and inserted between the gripping elements of said wire.

4. A smokers dry pipe pin, comprising a length of wire having its end formed into a pair of diverging fingers engageable in the smoke passage at the bowl end of the stem bit; of a pipe to hold the device in position, a cylindrical filter member for engaging in the smoke passage at the bowl section of the pipe stem, and gripping elements formed in said Wire and engaging said iilter for holding said filter, said gripping elements being formed with oppositely disposed arches for engaging said filter member for suspending and centering said lter member within said smoke passage for adequately removing the moisture from the smoke and still permit a free passage for the smoke through the smoke passage.
